TASK 1

Study the below given picture figure 1, answer the following questions.

Figure 1: Compartment fire.

? Write your understanding about various stages of fire development in a compartment and various contributing factors to enclosed fire growth.

? You are required to identify the state of control of fire (fuel or ventilation controlled) at the stage shown in picture 1 with a suitable explanation on its understanding.

? Also suggest the technical measures to reduce the growth of fire in a compartment. [1000 word]

TASK 2

Knowledge of Fire Load and Fire Load Density is very important in the field of Fire Safety Engineering.

In a room, there are some wooden tables, some plastic tables, some plastic chairs, a wooden cabinet. The floor is provided with a carpet. You can assume reasonable number of chairs and tables.

Use the following table for proper data collection and calculate the total fire load density if the floor area is 10m x 8m

Guidelines and data:

Tabulate the number of available items such as wooden chairs, tables, plastic tables, plastic chairs, carpet area etc.

Some other useful information you may require:

Table 1

Sl. No.	Item	mass	?hc in MJ/Kg.
1	Wooden table	2.5 kg per item	Ref: (Quintiere,2006, p.424)
2	Carpet	2.6 kg/m2	33 (Approx.)
3	Wooden cabinet	7 kg	22.3
4	Plastic Chair (Polyvinyl Chloride PVC)	1.4 kg per item	Ref: (Quintiere,2006, p.424)
5	Plastic table (Polyvinyl Chloride PVC)	3 kg per item	Ref: (Quintiere,2006, p.424)
6	AC outlet cover (Polypropylene PP)	2.8 kg per item	Ref: (Quintiere,2006, p.424)
7	Cushion on chair(Polystyrene foam)	0.4 kg per item	Ref: (Quintiere,2006, p.424)

TASK 3

Read Chapters ‘Energy Release Rate' from the textbook Karlsson, B., and Quintiere, J. G. (2000). Enclosure fire dynamics. CRC Press, Boca Ranton and also refer to the table 3.2. Hydrocarbon and Fuel diameter for each student is appended. You should calculate the HRR and duration of fire for fuel assigned.

Your report should contain all steps and a brief description on mass burning flux and HRR.

TASK 4

Foam, Dry Chemical powder, CO2, Wet Chemical, Water etc. are some of the main fire extinguishing agents available. Write about Dry chemical Powders and Wet Chemical Extinguishers. (use, applications, pros, cons etc) (300 words)
